Abstract: A noise attenuator for attaching a side wall panel to a frame that is exposed to vibratory loads and which includes a rigid core having a sleeve with two radially disposed end plates. A bracket encircles a portion of said sleeve between the end plates and is in non-contiguous relationship with the core. An elastomeric bushing is bonded to a portion of the bracket and the core with the exception of the outer faces of the end plates, which remain exposed. Voids are passed through the rear plate and extend axially between the bracket and the sleeve some length into the sleeve. Due to the geometry of the unit, the non-voided sections of the bushing are loaded in either a combination of tension and shear or compression and shear when the core is connected to a vibrating frame and the bracket is connected to a side wall panel.

Abstract: A system for limiting the exchange of shock and vibration motions and forces between a load and its supporting structure including an isolator. In one aspect, the isolator is designed for in-line mounting with a support strut. The isolator includes an elastomer member that may be substantially permanently maintained in a compression/shear state.
